OIL-BURNER.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed March 2, 1912. Serial No. 681,049.

To all whom it may concern Be it known that I, EDWARD C. FINoH, a citizen of the United States, residing at Kinsley, in the county of Edwards and State of Kansas, have invented new and useful Improvements in Oil-Burners, of

which the following is a specification.

This invention is an oil burner especially adapted for burning crude oil or other liquid hydrocarbon in stoves and furnaces, the invention consisting in the construction, combination and arrangement of devices hereinafter described and claimed.

One object of my invention is to provide an improved burner of this class which includes, in connection with a drip cup, an

oil spreader of novel construction and arranged to feed oil to the burner and drip cup and to promote vaporization of the oil, and, further, to provide a burner with a flame spreader and heat conductor of novel construction which greatly increases the etficiency of the burner by promoting and cansing the generation of the gas or conversion of the oil into vapor and by providing a chamber which retains the newly generated gas a stiflicient length of time to cause the same to be heated and insure the combustion thereof and also enables a low flame to bemaintained when desired, when the supply of oil by the feed pipe is purposely diminished.

In the accompanying drawings :Figure 1 is a vertical central sectional view of an oil burner constructed in accordance with my invention. Fig. 2 is a plan of the same, with the flame spreader and heat conductor removed. Fig. 3 is a detail plan of the drip cup.

In the embodiment of my invention,- I provide a drip cup 1 which is annular in form and is provided with an annular oil receiving chamber 2, the upper side of which is open. The central opening 3 in the annular drip cup has its wall provided, at a suitable distance from its upper side with an inwardly extending annular supporting flange or shoulder 4.

In connection with the drip cup, which forms the base of my improved burner, I employ an oil spreader 5. This is here shown as comprising a disk of suitable diameter and thickness. The oil spreader has a central opening 6 through which screws and extends the upper end of an oil feed pipe 7. In practice, this pipe is provided with a suitable valve wherewith to regulate the flow of oil therethrough to the burner or to entirely out off the same, as may be required. The oil spreader is provided on its upper side with a helical oil spreading groove 8 which extends from its center to its perimeter and serves to conduct the oil which is fed to the spreader from the upper end of the feed pipe around the spreader and outwardly thereon so as to cause the oil to traverse a considerable distance while passing on the oil spreader and thereby insure the conversion of all of the oil into vapor, by reason of the heatof the spreader. The spreader is provide-d on its upper side, near its perimeter, with a groove 9, and is also provided on its under side with a groove 10, spaced from its perimeter, which groove 10 is above the inner wall 11 of the drip cup and forms an annular drip shoulder 12 above the drip cup and justwithout the wall 11 thereof, the said drip shoulder 12 in connection with the groove 10 insuringthat any oil which may pass as such, from the oil spreader will drop directly into the chamber 2 of the drip cup and will not be carried to a point on the under side of the oil spreader above the opening 3. Hence, the waste of oil is by this means prevented. The oil spreader is provided with a suitable number of supporting legs 13 which bear on the shoulder or flange a and against the wall 11 of the drip cup and'serve to center the oil spreader with reference to the drip cup and to also support the oil spreader at a suitable height above the drip cup.

I also provide a flame spreader and heat conductor 14 which is here shown as a disk of suitable thickness and diameter, its diameter exceeding that of the oil spreader, so that the outer portion of the flame spreader and heat conductor overhangs the chamber 2 of the drip cup. This flame spreader and heat conductor is provided on its under side with a suitable number of supporting legs or depending studs 15 which bear in thebottom of the groove 9, and, hence, serve not only to support the flame spreader and heat conductor at a suitable distance above the oil spreader but also serve to center the flame spreader and heat conductor on the oil spreader as will be understood. The flame spreader and heat conductor is provided on its under side, with a centrally disposed retort or chamber 16 which is arranged above and is spaced from the oil spreader. At the center of the flame spreader and heat conductor is a depending point 17 which extends down a slight distance into the open, upper end of the feed pipe 7 and partially closes the same and yet permits the flow of oil therefrom. This point also prevents the entrance of particles of dirt or other foreign substances into the upper end of the feed pipe and, hence, prevents the upper end of the feed pipe from becoming clogged. The flame spreader and heat conductor is removable from above the oil spreader, and the oil spreader, as will be understood, is removable from the drip cup. To enable the flame spreader and heat conductor to be readily removed, I provide the same, on its upper side, with a centrally disposed upwardly projecting lug 18 which has an opening eX- tending therethrough engaged by a lifting wire 19 or other suitable device.

The various members'of my oil burner are preferably made of iron but may be made of any other suitable material. They may also be made of any suitable size and shape and the burner may be of any size required.

Ordinarily, my burner is intended to be used in the fire boX of a stove or furnace but it may be used in other places and in other connections and I would have it understood that I do not desire to be limited in this particular.

The operation of my improved oil burner is as follows :Initially the oil, when the feed pipe is opened by turning the valve therein, issues from the upper end of the feed pipe to the upper side of the oil spreader and is spread thereon as heretofore stated and drips therefrom into the drip cup until a sufficient quantity has accumulated in the drip cup and the oil is then ignited to initially heat all the parts of the burner. As soon as the burner is heated to the required degree, the oil be comes vaporized on the oil spreader and under the flame spreader and heat conductor and is converted into gas or vapor which is accumulated in the retort or chamber 16 to insure the heating of the gas or vapor and the gas or vapor issues from between the flame spreader and heat conductor and the oil spreader and burns in a clear, broad, annular flame and with very little, if any, smoke. The chamber 16 is not only advantageous in holding the gas or vapor a sutficientlength of time under the flame spreader and heat conductor to cause the same to be heated to the requisite degree but is also advantageous in that when the supply of fuel through the pipe is purposely diminished, a flame is maintained in the said chamber even after the supply of fuel has been so diminished that no flame appears beyond the periphery of the flame spreader and heat conductor. Hence, the oil burner may be kept in primed, heated condition, ready to be again employed by merely turning 011 an increased quantity of oil and without the necessity of initially heating the burner. The flame which issues from between the flame spreader and heat conductor is carried by a draft of air from between the oil spreader and the inner wall of the drip cup, so that the flame is spread outwardly and upwardly from the burner and a suflicient quantity of air is supplied to the gas or vapor to insure the substantially perfect combustion thereof.

Vhile I have herein shown and described what I now consider a preferred form of 'my invention, I wish to have it understood that changes may be made in the form, con struction and proportion of the several parts without departing from the spirit of my invention and within the scope of the appended claim. I

I claim An oil burner of the class described comprising an annular drip cup having an inwardly extending supporting flange spaced from the upper side of its inner wall. an oil spreader having supporting legs bearing on said flange and supporting said oil spreader above the inner wall of the drip cup and over the central opening of the latter, the said oil spreader being provided on its up per side with an oil spreading groove, a feed pipe extending up through the center of the oil spreader to supply oil to the upper surface thereof, and a flame spreader and heat conductor having supporting means to bear on the oil spreader and space the same above the oil spreader, the said flame spreader and heat conductor being also pro vided with a gas retaining chamber in its under side above the oil spreader and also with a depending point to enter the upper end of the said feed pipe.

In testimony whereof I aflix my signature in presence of two witnesses.
